Not disagreeing with you, but it is pretty reasonable to have staff monitor a newly released game that was basically in a beta state where players were betting real money.
Quite reasonable, but these thing happen in every industry (see teeGUMES's post while I was writing). If there was no malice, then it was handled properly. However, if there was malice then the casino deserves consequences. Given that they had very little to gain from this, I highly doubt someone intentionally acted malliciously (given that you could destroy your reputation for pocket change).
Especially ones who make a 0.009BTC deposit?
There have been and currently are companies large and small, that grow too fast too quick. They see the influx of money and profit coming in and they get greedy. They do not hire the correct amount of staff, instill the proper securities, and instead spend the money on marketing.
Could say the same for Facebook, heh.
